I took the time this morming to publish the test of HIS’s Radeon HD 4850 I started on month ago. I must say that Radeon HD 4850 shows high OpenGL performances and as always, vertex processing is incredibly fast (see surface deformer benchmark). At idle, GPU temperature is around 70°C while under load the temperature reaches 93°C (3-minute test with GPU Caps Viewer burner).

The full test is available here: HIS Radeon HD 4850 Graphics Card Review.
